Right-to-Left Override RTLO Removal Tool for filenames #Windows #malware

Malware writers can trick you in 2 ways into thinking your file is a "PDF looking" file using the Right-to-Left Override (RTLO) technique.

“Right-to-Left Override” RTLO example

Firstly, a maliciously constructed “.exe” can be built to display an PDF icon, so it looks like PDF default reader will open this file. If the filename is really long then, you can't see the extension (see image below). 

2ndly and may not be so obvious, malicious PDF filename is constructed as with a right-to-left override character is such a way that the file ends ".pdf" extension, but really is an ".exe".  


So in example below, the 2nd file looks like a ".txt" file, but is really a ".docx" file (the 1st file). The 1st file has been cleansed of the RTL Unicode character, and ends in ".docx". 

The PDF file is actually an ".exe" file, but looks like it will open with default PDF reader. 

Download RTLExample.7z ( it includes the above files with PDF ".exe" example. The files contain no viruses or malware. The PDF is safe ".exe", and just opens this page in Chrome). The "PDF" is safe ".exe", and just opens this page in Chrome. But GDrive marks these examples "Sorry, this file is infected with a virus", which good because they are detecting the RTL character and exe. But it a false positive, since there is no virus in the files. You can create you own examples by inserting the RTL character into the filename, see this video https://youtu.be/n2kV3Q2eTCY). 

Here's the same files as viewed from the command (cmd.exe) line. The box character represents the RTL character.

Note: Detection of malicious file is never done by a filename alone, so a good antivirus will flag the contents of this file, for known signatures. BUT you can remove the annoying RTL character with the free tool below! 

How is RTLO being abused by malware writers?

In apps that support Unicode like Window Explorer, the right-to-left override malware method uses  a RTL Unicode character, that will reverse the order of the characters that follow it. It's used mainly for Middle Eastern/Asian languages that you read right-to-left.

RTLO can be used to spoof fake extensions. To do this we need a hidden RTL Unicode character in the file name.

What is “Right-to-Left Override” RTLO?

The RTLO method is used to hide the true type of a file, so it might trick you into open text file (.txt) which really is a Word file (.docx) with malicious malware. More recently this file could hide a .wav file. Audio files such .wav file are being embedded with malware, is on the forefront of malware maliciousness. Read about that on my post here.

The method exploits a feature built into Windows Explorer. Since Microsoft Windows does a great job of supporting different languages from around the world, some of those languages that are written from right-to-left (RTL). 

Let’s say you want to use a right-to-left written language, like Hebrew or Arabic, on a site combined with a left-to-right written language like English or French. In this case, you would want bidirectional script support.

Bidirectional script support is the capability of a computer system to correctly display bi-directional text. In HTML we can use Unicode right-to-left marks and left-to-right marks to override the HTML bidirectional algorithm when it produces undesirable results:

left-to-right mark: ‎ (U+200E) Unicode character
right-to-left mark: ‏ (U+200F) Unicode character

How do you fix files that have the RTLO or other bad characters ? 

Here's a tool I built to clean up Right-to-Left Mark (and many others) and Unicode Control Characters from your files. It's super fast, small and written in native C++.
